Given that requirement, I'd be tempted to use a single upstream server
for all cluster members, plus orphan mode. That way, they all march
to the same beat, either the upstream server, or the elected orphan
parent if the upstream is unavailable.
That has a SPOF in terms of tracking correct time, but should keep
them mutually synced regardless.
